Couple/few things...
You can build up a tolerance to a lotta things, alcohol being one of them. Not that it doesn't affect you - it always does - but you learn to work around it. Many recreational drugs are that way as well.
Speaking of working around it, Keef has a tendency to play open tunings that allow him to do very little work. Makes life easy under pressure.
Money buys a lotta privilege, like miracle-worker health care. Your typical heroin addict just dies eventually. But, there are ways around that if you can afford it,
True. More on this. There is no theoretical dosage ceiling on opiate drugs, heroin included. The biggest danger of heroin is not actually the heroin itself, it's overdose, contaminated needles (hep C, hiv, etc), adulterants in the dope--AKA "the cut" or the idiots putting fentanyl in heroin (killed my favorite actor Philip Seymour Hoffman), inconsistency in potency, the criminal lifestyle it takes to keep up a habit, getting killed and/or robbed for your stash. And actually opiate withdrawal is almost never life-threatening as long as there are no comorbid medical issues such as liver failure, etc---you'll THINK you're dying, you'd rather be dead, but you won't die, you'll just surf about 2 weeks of pure misery. Alcohol, benzodiazepine, and barbiturate withdrawal, however, can kill you.
So, technically, if you get super-pure, uncut, consistent heroin, and use clean/new needles, and be judicious in your administration (hard to do), you really can function rather normally. The problem that comes in is tolerance. Ala Guns-N-Roses song, Mr. Brownstone..."I used to do a little but the little wouldn't do it so the little got more and more, I just keep tryin' to get a little better, a little better than before...we've been dancin' with Mr. Brownstone...he's been knockin', he won't leave me alone..." Ya'll know the deal. I been free from that dance for 8 years.
